Mauro Carvalho Chehab 88ca361900 [media] technisat-usb2: use DMA buffers for I2C transfers
The USB control messages require DMA to work. We cannot pass
a stack-allocated buffer, as it is not warranted that the
stack would be into a DMA enabled area.

On this driver, most of the transfers are OK, but the I2C
one was using stack.
